The Kartarpur Corridor has been constructed between India and Pakistan which was inaugurated by Prime Minister of Pakistan Imran Khan on 9th November as a part of events related to the 550th birth anniversary of Guru Nanak Dev Ji, the founder of Sikhism.  However, the Kartarpur Corridor was in dispute even before its inauguration  

A photo is going viral on social media, in which the Flag of Pakistan is seen on the roof of Kartarpur Gurudwara. It is being claimed that Pakistan has put the Pakistani flag instead of putting a Khanda flag ( A special flag which is seen in every Gurudawara called Nishan Sahib) in the Gurudawara. A facebook user name Sangram shares a post with a claim "Look at this- Pakistan puts their flags on the rooftop of Kartarpur Gurudawara, instead of the Khanda flag. where are the so-called Khalstani now? Did they all become cowards? or are Sikhs scared&converting to Islam?"

The same picture is also getting viral on Twitter. A user name Anamika Patel shares a photo with the same claim.

The rooftop of immigration center

After doing reverse image research on google we found that the viral picture is not of Kartarpur Gurudawara but of the Immigration center.

We found an article from the Pakistani Website "The Express Tribune" in which the same photo can be seen. According to the report published on 4 November, the first phase of the construction of the Kartarpur Corridor project and renovation of Gurdwara Darbar Sahib Kartarpur, which is the world’s largest Sikh shrine, has been completed. The report has complete information about the immigration center.

As per the article,  a 150-feet-high Pakistani flag has been hoisted near the immigration center. The building is painted in white and the finishing has been done in gold which matches the structure in the viral picture.

Moreover, there is no similarity between the gurudwara building and the structure in the viral image. You can see recent pictures of Gurudwara on Google maps.

Pakistan Prime Minister Imran Khan also shared some photos of Kartarpur Sahib on his Twitter account with a caption "I extend my heartfelt congratulations to my government on preparing Kartarpur in record time for the 550th birthday celebration of Gurunanak Ji".(Translated from Urdu). These photos are also completely different from viral photos.

In conclusion, the claim is false that the Pakistani flag is printed on the roof of Kartarpur Gurudawara. The viral picture is not of the Kartarpur Gurudawara but of the immigration center.
